The truth is that we need to burn as much as possible in order to push the CO2 levels ultimately to around a 1000 ppm from the original level of 280 ppm. So what we are doing continues to work just fine.
Otherwise, this item works up the absurdity of some of the alternates. Not too unlike the ultimate absurdity of steam power before we used oil.
The energy shifts that i do see, besides accessing Tesla's original patent which will eliminate the bulk of gasoline powered transportation at the least, is the accessing of geothermal heat exchangers for household heat. That nicely eliminates the whole fueling cycle once and for all.
- Accommodating the 46,480 solar photovoltaic (PV) plants envisioned in the WWS for just the U.S. would take up 650,720 square miles, almost 20% of the lower 48 states. This is close in size to the combined areas of Texas, California, Arizona, and Nevada.
- Western Europe has extensive experience with investments in renewables to replace fossils. By the end of 2014, the generating capacity renewable energy sources amounted to 22% of Europe’s capacity, while actual output was only 3%.
- Meeting 8% of the U.K.’s real energy needs would require having to build 44,000 offshore wind turbines. Doing this, would fill the entire 2,000 mile U.K. coastline with a strip about 2.5 miles wide.
- To replace the 440 MW of U.S. generation expected to be retired over the next 25 years would take 29.3 billion solar PV panels and 4.4 million battery modules. The area covered by these panels would be equal to that of the state of New Jersey. It would require 929 years to build this many panels at the rate of one per second.
- A central component of WWS calls for the electrification of all transportation uses. This is technically impossible now as the technologies have not yet been developed that would allow battery storage applicable to heavy-duty trucks, marine vehicles and aircraft.
- Even in the case of automobiles, despite taxpayer subsidies of $7,500 per vehicle and up, the number of all-electric vehicles sold has consistently fallen far short of governments’ goals.
- The costs of electrifying passenger rail systems are so high that no private railway would ever take them on. Electrification of freight railway systems makes even less sense, and would cost at least $1 trillion each.
- The proponents of WWS grossly underestimate the costs of integrating renewable energy sources into the electricity system. The costs of backup generation, storage, load balancing and transmission would be enormous.
- About 60 pounds of batteries are needed to store the energy equivalent to that in one pound of hydrocarbons. Meanwhile, 50-100 pounds of various materials are mined, moved, and processed by hydrocarbons for one pound of battery produced. In rough terms, it requires the energy equivalent of about 100 barrels of oil to fabricate a quantity of batteries that can store a single barrel of oil-equivalent energy.
- Even at the present rate of growth, mining required to make batteries will soon dominate the production of many minerals. Lithium battery production today already accounts for about 40% and 25% respectively, of all lithium and cobalt mining.
